Miss Obedient Paris Hilton is now going into rehabilitation to give up her gambling habits. Both the Hilton sisters are obsessed with poker. Paris Hilton gambled away her $150,000 Bentley in a poker game at her father’s casino in LA lately, whereas Nicky was the guest celebrity at a poker game. Oh! This is kind of disappointing for her fans who were dying to play a poker game with her. There are no reports concerning Nicky also undergoing the therapy. Does it mean that her parents are more bothered about Paris?
